Application February 9, 1938, Serial No. 189,575

4 Claims.

This invention relates to holders for rolls of paper and similarmaterial 'to permit the ready dispensing of said material in sheets asfor use in wrapping merchandise.

Holders of this general type for dispensing such material in sheet formhave long been in use, thesecommonly including means for supporting aroll of wrapping material and a tearing blade which is yieldably pressedagainst the roll. When the sheet material is torn from a roll held inone of these devices, it is pulled against the tearing blade. Thisproduces a tendency for the blade to be lifted out of contact with theroll by the pull exerted on the paper in the tearing operation. Whenthis happens, a ragged edge on the paper results. In holders of thistype put out heretofore it has always been necessary to compromise inselecting the amount ofpressure with which the tearing blade is pressedagainst the roll. The reason for this is that the pressure with whichthe tearing blade is pressed against the roll varies as the diameter ofthe roll de-'- creases, whereas the requirements for tearing anyparticular kind of wrapping material are sub It is an object of myinvention therefore to provide a paper holder and dispenser for holdingpoper in the roll form and dispensing it in sheets, which is adaptableto handle wrapping material in roll form and dispense this in sheets andwhich is readily controllable to cause it to perform this function withvarious weights of wrapping material which differ substantially intearing coefficient.

It is another object of my invention to provide a holder and dispenserof wrapping material, for carrying out the above mentioned objects, andwhich is not only pleasing to the eye in external appearance, but verysimple in construction.

A still further object of my invention is to provide such a holder anddispenser'for wrapping material which is especially adapted to bemounted on the under surface of a table, counter or the like.

In this present application, as distinguished from my copendingapplication, Serial No. 189,574, the subject matter claimed relates to apaper dispenser embodying the characteristic feature of a springshifting and tensioning mechanism in combination with other parts ashereinhead beam I2.

after described, by which unfiexed leaf springs may be installed throughopenings in housings, and

shifted away from the openings to prevent dislodgment and to flex thesprings so that they perform their function of urging-a tear blade intoengagement with the roll of paper carried in the dispenser. Thisstatement is not to be construed as a limitation of any of the claimsaccorded their proper range of equivalents.

The manner of accomplishing the foregoing objects as well as furtherobjects and advantages will be made manifest in the followingdescription taken in connection with the accompanying drawing in which:

Fig. 1 is a perspective view of a preferred embodiment of the invention.

Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. 1 andshowing the leaf springs of the invention in operation. I

Fig. 3is a view similar to Fig. 2 illustrating the manner of assembly ofsaid leaf springs with said invention.

Fig. 4 is a horizontal cross sectional detailed View taken on the line4-4 of Fig. 2. v

The preferred embodiment of my invention illustrated in the drawingcomprises a paper dispenser l 0 which includes a pair of side standardsII which are connected at their upper ends by a The sidestandards H arein the form of housings having-inside walls l3, outside walls M, abottom l5, front walls I6 and rear walls l For the purpose ofsupporting'a roll 20 of wrappingmaterial-through which a shaft 2|extends, slots 22 are provided in the front walls I6 and inside walls l3of the housings H- for accommodating opposite ends of said shaft. Thefront walls it: have slots 25 through which arms26 provided on oppositeendso'f a tear blade 2'! extend into interior chambers 28 of thehousings II. The arms 26 have trunnions 30 which extend into suitableopenings into the outside walls M of the housings H so that the arms 26and tear blade 21 are pivotally mounted as a unit on these trunnions.The arms 26 have short projections 35 on the opposite sides of thetrunnions 30 from the tear blade 21. Mounted on these extensions arerollers 36. g

Provided in the bottoms of the housings H are apertures 38 through whichleaf springs 40 are adapted to be inserted into the chambers 28 so thatthe upper ends of these springs are disposed opposite the rollers 36. Inthe preferred embodiment illustrated herein, two of the leaf springs 40are shown as being used in the device ID in each of the housings II. Itis to be under threaded holes in blocks 52 located in the cham- I Theinner end bers 28 just inside the walls H. of each screw member 5!preferably has a half round head 53 which engages the springs directly.On its outer end, member 5i has a knurled manual control knob by whichit may be rotated for advancing it inwardly or retracting it outwardlythrough the blocks 52.

The assembly of the springs-40 with thedevice if! of my invention isillustrated in Fig. 3. Here it is seen that the screw members 5| havebeen retracted to their outwardmost positions and there is no roll 20 inthe device ill so that the arms 26 and tear blade 27 are swung to theirinwardmost positions. Springs 48 are now' inserted longitudinallythrough the apertures 38 into the chambers '28. When these springs havepassed through the apertures 38, the screw morn bers 5! are rotated soas to be'advanced through the blocks 52 against the springs 41] therebyshift ing the lower ends of the latter out of alignment with theapertures 38 and into engagement with the fulcrum lugs 46. The tearblade 21 may then be swung upwardly until the arms 26 engage the upperends of the slots 25 and a roll of paper 20, with an axle 2! extendingtherethrough, inserted into the device with the ends of the axle restingin the slots 22. After this the tear blade 21 may be swung downwardlyinto contact with the roll 20 and the correct pressure of the springs 43against the arms 26 obtained by manipulation of the knurled thumb screwheads 55.

From the foregoing description it is clear that the device In of myinvention is relatively simple in construction and provides a means forregulating the pressiu'e with which the tear blade 21 is pressed againstthe roll of wrapping material 29 supported in the device so that thispressure is adequate for the tearing of whatever weight of paper happensto be contained in this roll and yet is not an excessive pressure so asto cause a wrinkling of the paper when the roll rotates.

Another advantage of my invention is the great ease of assembly of thesprings with the device as well as the ease with which disassembly ofthe device may be effected in case it is necessary to replace a weakenedor broken spring.

What I claim is: 1. In a holder adapted to support wrapping against saidroll; fulcrum means on said housing on which said springs fulcrum, therebeing apertures in said housings through which said springs are adaptedto be inserted lengthwise into said housings; and manually controllablemeans for engaging said springs after they are in said housings forforcinggsaid springs into engagement with said arms and said fulcrummeans to shift said springs out of alignment with said apertures.

2. A roll paper dispenser comprising housings, means carried by saidhousings to support a. roll of paper, arms pivoted in the housingscarrying a paper tear blade, openings in the housings to installunflexed leaf springs in the housings, fulcrum lugs in the housings,leaf springs in the housings, and means accessible outside the hous--ings to shift the springs away from the openings to prevent dislodgmentof the springs and to cause pressurable engagement of the springs withthe fulcrum lugs and the arms to urge the tear blade into engagementwith the paper.

3. A roll paper dispenser comprising housings, means carried by saidhousings to support a roll of paper, arms pivoted in the housingscarrying a paper tear blade, openings in the housings to installunflexed leaf springs in the housings, fulcrum lugs in the housings,leaf springs in the housings, and screws accessible outside the housingsto shift the springs away from the openings to prevent dislodgment ofthe springs and to cause pressurable engagement of the springs with thefulcrum lugs and the arms to urge the tear blade into engagement withthe paper.

4. A roll paper dispenser comprising housings.

means carried by said housings to support a roll of paper, arms pivotedin the housings carrying a paper tear blade, openings in the housings toinstall unflexed leaf springs in the housings, fulcrum lugs and the armsto urge the tear blade into engagement with the paper.
